Abstract

A method for controlling gear-shifting processes of a powershift gearbox which can be coupled to a drive motor and has gear steps including two friction clutches and a plurality of clutches, and at least one gearbox actuator for actuating the gear steps. The method includes the following steps: the torque of the drive motor is received by the new friction clutch associated with the new gear step to be engaged; before the disengagement of the old gear step and before or during the torque reception, a pre-determined pre-tensioning force is applied to the clutch of the old gear step by the gearbox actuator; and the old gear step is disengaged when the motor torque and the clutch torque are balanced.
